Advancing the retrieval of aquatic optical properties using multi-angle polarimetry
All applications must be submitted in Zintellect
Description:
Satellite measurements from radiometers observing the ultraviolet-to-shortwave infrared spectral range have revolutionized our understanding of Earth’s atmospheres and oceans over the past four decades. The majority of these satellite radiometers, however, rely on the scalar treatment of light, thus neglecting the polarization components of that light. Polarized light emerging from the Earth system carries a plethora of information about both the atmosphere and the ocean that is, in particular, underutilized in ocean remote sensing. Several new satellite missions are in development that will host advanced multi-angle polarimeters – including the NASA Plankton, Aerosol, Cloud, and ocean Ecosystem (PACE) mission, the NASA Earth System of Observatory’s Atmosphere Observing System (AOS), and EUMETSAT Polar System-Second Generation Metop-SG programme. Furthermore, there is now an increasing availability of in- and above-water instruments to measure the polarization state of seawater. Following, the time is right to pursue novel remote sensing methods that strengthen our understanding about information contained in polarization signals for use in ocean remote sensing applications.
The Ocean Ecology Laboratory (GSFC Code 616) seeks an NPP fellow to pursue novel remote sensing and bio-optical approaches for deriving aquatic optical properties from multi-angle polarimetry, with a primary focus on satellite data records. The candidate should have educational experience in remote sensing, radiative transfer theory, and polarimetry. An ideal candidate will also have experience in bio-optical modeling, polarimeter architecture and design, and performance assessments using data collected at-sea, while also being adept at collaborating with others and communicating results to colleagues, program managers, the community, and the general public.
